Solid biofuels — Determination of grindability — Hardgrove type method for thermally treated biomass fuels

This document describes a method for determination of grindability of graded thermally treated and densified biomass fuels such as classified in ISO/TS?17225-8, for the purpose of preparing fuels with a defined particle size distribution for effective combustion in pulverized fuel boilers. The grindability characteristics determined by the test method provide guidance as to the pulverizing mill performance when utilizing such fuels.

Apart from pelletized materials as described in ISO/TS 17225-8, the method can also be applied to non-compressed or non-densified thermally treated biomass as specified in ISO?17225-1:2021, Table?14 and Table?15.

The results created with this method are not relevant for large wood chips, since limitations apply for large pulverizing coal mills, which are typically not used for grinding materials such as chips.
